SPINDLE DRIVE FOR WINDING Application led September 8, 19231 Serial No. 661,714.

Tioall 'whom t may con/cern.'

' Be it known that I, ANKER Pn'rERsnN, a

- citizen of the United States of America, and

resident of Vinthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Spindle Drives for Winding Machines, of which the'following is a specification.

Thisinvention pertains to yarn and thread winding machinery and relates more particularly to mechanism for driving and automatically stopping the winding spindle.

The principal object of the present invention is toprovide high speed Winding mechanism of simple design capable of Winding thin and tender yarns and including automatic stop mechanism for stopping the Winding spindle when the yarn mass has attained a predetermined size as well as when the yarn breaks or becomes unduly slack, the stop mechanism comprising detector devices so arranged that they do not impose an injurious strain upon the yarn.

In the accompanying drawings a preerred embodiment of the invention is illustrated by Way of example, and in the drawings Fig. 1 is a fragmentary plan view of one end of a winding frame showing one element of' Winding mechanism constructed in accordance with the present invention;

Fig. 2 is a front elevation of the parts shown in Fig. 1; Fig. 3 is a fragmentary end elevation from gie left-hand end of the device as viewed in Fig. 4 is an end elevation from the righthand end of the device as viewed in Fig. 1. vcertain. parts being shown in sectif n;

Fig. 5 is a fragmentary detail sectional view on the line 5-5 of Fig. 2; and

Fig. 6 is a' vertical section on the line 6 6 of Fig. 2.

The numeral 1 indicates a table orsupport forming a 'part of a winding frame which may be of any desired length and which may support .any desired number of the Winding units of `which one is hereinshown,

and described in detail. A shaft l is journaled beneath the table 1 ,extending longitudinally of the latter and is provided with a driving drum or series of pulleys such asl Each winding unit comprises a frame 2 having spaced standards 2f* provided at their upper ends' with bearings 3 and 4 respectively. A winding spindle S is mounted in journals in the bearings 3 and 4 and carries a fast pulley 5 and a loosepulley 6, the pulleys preferably being disposed between the bearings 3 and 4. The spindle S projects to the right of the bearing 4 as viewed in Fig. 2 and is provided with a face plate 7 having g. central journal opening and a projecting A support 9 is pivotally connected at 10 to the frame 2 and is provided with a bearing l 11 having a central journal opening opposed to the opening at the center of the face .plate 7 The support 9 is furnished with a stop 12 for limiting its movement toward the face plate and is held -in normal position by means of a spring 13. A second stop 14 may be provided for limiting the outward swing of the support 9. I

As herein illustrated a spool 15 ofthe type commonly used in the carriers otbraiding machines is mounted between the tace plate 7 and the bearing `11. This spool is :Eurnished with axial shaft projections 16 and 17 which engage the openings in the face plate 7 and in the bearing 11 respectively.

. One end of the spool is furnished with an directly upon an extension of the spindleitself or upon a tube, spool or other device mounted upon such extension, the term spindle as herein employed being in.

tended to include the spindle proper as Well as any axial extension, integral or otherwise, thereof, as for example the spool herein illustrated.

A driving belt 18 normally engages th fast pulley 5 and receives its moti-on from the driving pulley or drum 1b. The belt or power transmitter 18 may be shifted to and from the loose pulley 6 by means of a belt shifter pivoted at 19 upon the frame 2. This belt shifter preferably consists of a bell crank lever having the upwardly ertending arm 20 provided with hook like ears 21 and 22 which loosely embrace the opposite edges of 'the belt. The 'upper end of the arm .20 is furnished with a handle 23 by means of which the belt. shifter may be moved manually. v

The belt shifter also comprises the arm 24 ywhich forms one element of a toggle device.

The other element of'this toggle device consists of a rod 26 pivotally secured to the end of the arm 24 at the point 25 and guided at itsopposite end in an opening in the lug 27 projecting upwardly from the frame 2. The rod- 26 is free to slide and also to swing in the opening in the lug 27. A coiled spring 28o encircles the rod 26, bearing at one end against the lug 27 and at the other against an enlargement or collar upon the rod adjacent to itsv pivotal connection to the arm 24.

A shalt 28 is mounted in brackets 29 and 36 projecting from the rear of the frame 2.

'TA 'split collar 3l is secured to the shaft 28 and a yarn-engaging detector plate 33 is secured to the spllt collar. A spring 34 encirclesthe shaft 28 and has one end 35 bearing against the under side of the trame 2 while its other end 36 bears against the collar 3l and tends to swing the detector vplate 33 against the winding yarn mass M.

An arm 34` projects downwardly and 'forwardly trom the collar 31 and has its forward'end 38 disposed beneath the extreme end of the arm 24 substantially at the point of connection of the latter to the rod 26.

A shaft 39 is journaled in an opening in the left-hand standard 2a of the trame and a collar 39a is secured to the end of this shalt at the-outer side ofthe standard-2a. A de-y and Yis or a length to engage the yarn Y on vee its way to the winding mass in any position which it may be caused to assume by the traverse mechanism.

y A block 43 is secured to the shaft 39 below and in the plane of the pulley 5 and this block is furnished with a curved face 44 constituting a brake element engageable with the peripheral surface of the pulley 5.

At its right-hand end .the shaft 39 is urnished with a crank arm' 45 to which the u 'per end of a link 46 is pivotally connected. 'll e lower end of this link is furnished with a forwardly extending toe 47 which is disposed adjacent to the forward endof the arm 37 and immediately below the end of -the arm 24.

Pairs of grooved rolls 48 v and 49 are mounted at spaced intervals along the length of the winding trame, one pair of such rolls bein shown as mounted upon the left-hand -stan ard 2a or"- the winding unit here illustrated. A traverse rod or bar 50 is mounted between the rolls of the several pairs to rec1 recate longitudinally 'of the machine.

.1s bar 50 carries a slub removing yarn guide corresponding to each winding unit. Each of these yarn guides preferably con.-

sists or a pair of plates 52 and 53 secured neueste -in split collars 5l mounted u on the bar and spaced apart at their ad3acent edges to provide a yarn guiding slot 54. 'llhis slot is of accurately uniform width from top to bottom so that regardless of the size of the winding yarn mass the yarn is properly stop device 57 is disposed above the eonnection between the arm and the rod to limit upward movement ot the pivotal connection of these elements.

rlFhe device operates substantially as foi- -lows, it being assumed that the parts normally occupy the position indicated in the drawings. As thus arranged the yarn f l'coming from the supply and suitably tensioned in any desired manner, as for en ample by frictionally retarding the supply bobbin or spool, passes over'the rail 56 and beneath the detector linger 2 whose weight is supported by the yarn and thence through. the guide slot 54 to the yarn mass hi. The detector plate 33 bears with light pressure against the winding yarn mass. The belt shifter arm 2() is so disposedlthat the belt 18 engages the last pulley 5 and the arm 24 of the belt shifter inclines downwardly and to the right as viewe in lFig. 2. As thus positioned, arm 24 and rod 26 are not exact alignment but are disposed angularly with respect to each other and the parts are maintained in this position by means ot the spring 28u.

As the yarn mass increases in diameter in the Vorderly operation of the machine, the plate 33 is gradually swung in a clockwise direction as viewed in Fig. 6 until the forward end 38 of the arm 37 engages the under side oif the arm 24 whereupon the latter' is lifted in opposition to the spring 28 until the arm 24 and the rod 26pass a position of alignment whereupon the reaction of the spring 28nu causes the toggle device comprising parte 24 and 26 to be broken and quickly swings the arm 20 to the left so as to carry the belt onto the loose pulley 6. The winding spindle is now stopped and the operator removes the filled spoolv or yarn mass by swinging the bearing member 11 to the right. An empty spool can now be inserted and the winding operation resumed, the belt being replaced upon the fast pulley by manual operation of the handle 23 which at the same time restores the parts 24 and 26 to normal position.

llf during the winding, the yarn should break or become unduly slack, the detector finger 42 which is supported by the yarn in- `lellnediate the rail 56 and the guide slot Yees.

54 is permitted to drop. This rocks the shaft 39 and swings the crank arm 45 so as to raise the link 46 to cause its toe 47 to engage the under side of the arm 24, whereupon the toggle is broken in the same manner as above described and the belt is shifted onto the loose pulley. When the yarn breaks, it is particularly desirable to Stop the spindle quickly and for this pur'- pose the brake comprising the block 43 is provided. This brake is brought into engagement with the pulley 5 when the detector finger 42 drops so that immediately after the belt is shited the spindle is brought to rest.

The device above described is capableof winding yarn at very high speed and, as the detector devices is only called upon to overcome the resistance of the relatively light spring 28"', it may be made very light in weight, so that it will not injuriously strain the tenderest and finest yarns. The mechanism is extremely compact and easy to construct and is so easily manipulated and certain in action that a single operator can care for a very large number of winding units.
